Butterworth_low_pass_and_high_pass_filters

介绍了Matlab中的各种运算，对Matlab中的运算操作进行了细致的总结(Describes the various operations Matlab, Matlab, computing on a detailed summary of operations)

利用MATLAB实现语音去噪，主要是基于小波去噪(Speech Denoising realize the use of MATLAB, is based mainly on the wavelet denoising)

说明：  里面有33个在中国知网和其他学习网收集的论文，里面都是语音端点检测的学术论文，对于要进行语音处理的人有很高的价值。(paper from cnhk,about speech endpoint detection. have a high value)

翻译了3GPP 25213-700扩频部分的协议内容,此标准翻译的还算标准,可以直接使用(translated 3GPP 25213-700 spreading part of the agreement, Such standards are fairly standard translation can be used directly)

为了得到具有一般相关量测噪声线性系统的递推滤波算法, 将该问题转化为具有相关量测 单值随机向量的滤波问题,根据单值随机向量的线性无偏最小方差估计算法,导出了量测噪声为一 般相关鞅差序列的线性系统的最优递推状态估计滤波算法.通过数值仿真,将该算法与假定量测噪 声不相关时的Kalman 滤波算法进行了比较,证明了该算法的有效性(In order to obtain the recursive f i ltering alg orithm for a linear system w ith general correlat
ed measurement noises, the problem is t ransformed to that of filtering for a single random vector w ith correlated measurements. According to the linear unbiased minimum variance estimation algorithm for a single random vector, a recursive filtering algori thm is presented. A digital simulat ion technique is used such that the new algorithm can be compared w i th the Kalman f i ltering algorithm, assuming that the measurement noises are uncorrelated. Validi ty of the proposed algorithm is thus proved)

基于小波变换和OMP算法的稀疏表示,不仅包括适用于黑白图片的程序，也包括适用于彩色图片的程序。(the sparse representation basing on wavelet and omp,not only for the gray image,but also color image )

Estimating State-Space models through Maximum Likelihood_matlab code

本程序，包含QPSK，OQPSK的产生过程，I、Q领路信号抽取，他们的频谱，包络情况，经过带通滤波器后的变化，经过非线性放大器后的频谱变化等。是一个很好的学习例程！(This procedure, including QPSK, OQPSK production process, I, Q signal extraction lead the way, their spectrum envelope case, after band-pass filter after the change, through non-linear changes in the spectrum after the amplifier. Is a good learning routines!)

zxing二维码扫描的源代码,包括zxing核心包的jar和ZXingDemo源码,非常详细.(zxing dimensional code scanning of source code, including zxing core package jar and ZXingDemo source, very detailed.)

曲线波变换用于图像去噪是新兴起的一种多尺度工具，里面涵盖了比较好的毕业设计资料，希望对大家有用(Curve wavelet transform for image denoising is a new emerging multi-scale tool, which covers a relatively good graduation design information, we hope to be useful)
